Enhancement of photocatalytic H2 production activity of CdS nanorods by cobalt-based cocatalyst modification

The excellent photocatalytic H₂ production activity of Co₃O₄–CdS nanocomposite was mainly attributed to the formation of p–n heterojunctions between the p-type Co₃O₄ nanoclusters and n-type CdS nanorods, which could promote the photoinduced charge transfer and separation.
